I'm a wanabee machinist who has a mill
drill and an imported keyless drill chuck
that after a while doesn't hold the bit
any more. Short of buying a better drill
chuck, is there anything that can be done?

Regards,

Pat Young

Pat,

It's unlikely that you'll be able to buy replacement jaws for an import chuck unless it's a "brand name". MSC sells the Accupro brand (I have not used it) that is pretty low priced & has replaceable parts: http://www1.mscdirect.com/CGI/NNPDFF?PMPAGE=1596

Albrecht & Jacobs chucks are often listed on eBay.

What ever you do dont buy the thread mounted hand tite keyless chuck. The second down on the left. It may be a Jacobs but they really let the side down on those. They come out on many electric hand drills and are the biggest POS out. http://bbs.homeshopmachinist.net//mad.gif I think the discription hand tite refers to there gripping force on the drill not the mentod of tightening. http://bbs.homeshopmachinist.net//frown.gif
That said there are good keyless chucks out there. If you can't afford a quality keyless chuck get a good keyed one.

John.

I have a keyless chuck on a Bosch drill and it was acting up. I pointed it at the ground and shoved a needle air compressor up into and blew the hell out of it. Then did the same thing with WD40 and blew it out again. I light coat of 3 in 1 oil and it works great again. Don't know if this would work for you.
